My soft top rear plastic up right post makes noise when I hit bumps. You can lift the base off of the metal rail. The top is bolt down to the roll bar but is there a bolt on the bottom I'm missing. It moves up and down where the hard top would bolt up too. Any thoughts

 

I would have to see pics to compare to mine. Mine doesn't do it.

 

Not quite sure what part you are talking about.

 

the back plastic post that runs up from were the hard top would bolt to and goes up to the top
